[0091] Such as image 3 As shown, it is an example of extracting feature points in step S5; Figure 4 As shown, it is an example of performing feature point matching in step S5; Figure 5 Shown is the dense point cloud and camera position obtained based on the three-dimensional information obtained by the depth camera. The circle with a number indicates the camera position. In practical applications, it is clearer than the sparse point cloud obtained by a dome camera, and a more accurate three-dimensional model can be established. On the basis of the precise camera position, the mapping can be performed according to the camera position, because each dome camera has the color information of the two-dimensional panoramic photo that it is located at the camera position.
[0092] In step S9, the three-dimensional model is automatically mapped, and the two-dimensional panoramic photo taken by the dome camera at a certain position in space is pasted to the corresponding position of the ...
